Return of the Giant Hogweed

Turn and run
Nothing can stop them
Around every river and canal
Their power is growing
Stamp them out
We must destroy them
They infiltrate each city
With their thick dark warning odour
They are invincible
They seem immune to all our herbicidal battering
Long ago in the Russian hills
A Victorian explorer found
The regal Hogweed by a marsh
He captured it and brought it home
Botanical creature stirs
Seeking revenge
Royal beast did not forget
He came home to London
And made a present of the Hogweed
To the Royal Gardens at Kew
Waste no time
They are approaching
Hurry now
We must protect ourselves
And find some shelter
Strike by night
They are defenseless
They all need the sun to photosensitize their venom
Still they're invincible
Still they're immune to all our herbicidal battering
Fashionable country gentlemen
Had some cultivated wild gardens
In which they innocently planted
The Giant Hogweed throughout the land
Botanical creature stirs
Seeking revenge
Royal beast did not forget
Soon they escaped, spreading
Their seed preparing for an onslaught
Threatening the human race
Might Hogweed is avenged
Human bodies soon will know our anger
Kill them with your Hogweed hairs

GIANT HOGWEED LIVES!
